NAD+: Research Overview for Men and Women

What Is NAD+?

Nicotinamide adenine dinucleotide (NAD+) is a coenzyme found in every living cell. It plays a central role in cellular energy metabolism, DNA repair, and the regulation of biological processes that govern how cells age and function. NAD+ levels naturally decline with age in both men and women, making it a significant focus of longevity and metabolic research.

NAD+ and Cellular Energy

NAD+ is essential to the mitochondrial processes that convert nutrients into ATP — the primary energy currency of the cell. Research has shown that declining NAD+ levels are associated with reduced mitochondrial function, which is linked to fatigue, metabolic slowdown, and age-related cellular decline.

Research Areas in Men

  • Testosterone and hormonal signaling — NAD+-dependent sirtuins have been shown to interact with androgen receptor pathways in preclinical models.
  • Cardiovascular function — Studies have examined NAD+’s role in endothelial health and nitric oxide production.
  • Muscle recovery and performance — Research has explored NAD+’s interaction with PARP enzymes involved in DNA repair following exercise-induced cellular stress.
  • Cognitive function — Preclinical models have investigated NAD+’s neuroprotective effects in the context of age-related cognitive decline.

Research Areas in Women

  • Menopause and hormonal transition — Research has explored the relationship between declining NAD+ levels and metabolic changes associated with perimenopause.
  • Fertility and reproductive biology — Preclinical studies have examined NAD+’s role in oocyte quality and mitochondrial function in reproductive cells.
  • Skin aging — NAD+-dependent sirtuins have been studied for their role in regulating collagen synthesis and oxidative stress pathways.
  • Bone density — Some research has explored NAD+’s interaction with SIRT1, an enzyme implicated in osteoblast activity and bone remodeling.

The Sirtuin Connection

Much of the interest in NAD+ centers on its role as a substrate for sirtuins — a family of proteins often referred to as “longevity enzymes.” Sirtuins regulate inflammation, DNA repair, circadian rhythm, and metabolic homeostasis. Because sirtuins require NAD+ to function, maintaining adequate NAD+ levels is considered essential to their activity in research models.
